Functional Description Technology Control
PID Output frequeny at 100%
(cn.14)
This block converts the percental controller output value into a frequency. The
adjustment of cn.14 determines which frequency is output at 100 % controller output
value. A frequency from -400.0...400.0 Hz (dep. on ud.2) can be adjusted. At cS.0 bit
0...1 = 1 the output value added with the ramp output frequency (ru.2) forms the
output frequency (ru.3).
The whole controller, the I-component as well as the controller fade-in can be reset via
a digital input. When resetting the masking the fade-in time is valid. For that purpose
the decimal value of the corresponding inputs according to the table below has to be
entered.
cn.11 PID reset / input selection
cn.12 I reset / input selection
cn.13 Fade in reset / input selection
Reset by way of digital inputs
(cn.11...13)
With cn.10 it is possible to set the reset conditions for the PID-Controller. Thus simple
speed regulations can be realized for both directions of rotation.
cn.10 Function
0 PID-Controller is not reset
1 PID-Controller = 0 (is continously reset)
2 PID-Controller is reset in case of modulation off
For speed regulations adjust the value „2“, with that the I-component of the controller
is reset at LS or nOP. The value „1“ serves mainly for the start-up, to reset the controller
manually.
